Power Supply problem or some other piece of hardware...?

Hi, I have recently upgraded my video card, Ram, motherboard and Hardrive. My motherboard is a MSI KT6 Delta-FISR and I brought 2x512mb pc3200 Vdata Ram chip, a Seagate 80GB SATA Hardrive, ATI 9700pro, and a Thermaltake SILENT PUREPOWER SERIES TT-420AD W0009RAC 420 watt power supply. I orginally purchased an ICUTE 400 watt PSU which proved insufficent for my system(or so I thought). a week or so I posted a topic asking about what new PSU I should get(becuase of my crappy ICUTE PSU) and was told that the Thermaltake PSU I was considering buying should be sufficent for my needs. Now thats all well and good(thanks for the advice guys ) but I am now expriencing exactly the same syptoms i had with my ICUTE PSU.
The voltage on the shiny new Thermaltake PSU is as follows:+3.3V@30A;+5V@40A+12V@18A
The voltage on my shiny new(but crappy) ICUTE PSU is as follows:+3.3v@28A;+5v@40A;+12v@18A
Very similar I know, but I presumed that because ICUTE isn't exactly the best brand around they were in someway lying about the Amps avilable. So I take my Thermaltake PSU out of its box looking foward to finally getting my newly upgraded computer NZ$1000 later, working.
Alas it was not to be. Screw in the PSU, connect all the connecters to the drives/video card/motherboard and finally plug it into the power cable and press the power button on the case. The computer powers up fine( and also A LOT quieter than the ICUTE PSU) and runs the POST screen. Goes through all of that crap and then starts to load the windows setup. Setups first screen flashes for 1 second then the computer turns itself off. OOOOOO DEAR! EXACTLY the same syptoms as the ones I experenced with my ICUTE PSU.
Now before I had brought my new Thermaltake PSU I had tried two other PSU's.
Now bear in mind these are fairly generic cheap PSU's
First one I tried was a 300watt Hynea(i think!) PSU which had about 14A on the 12v rail and predicably It did the same thing as my ICUTE PSU.
Second psu was a "Olympics" 320watt PSU. Now very very strangly this PSU which had 12v@16A;5v@30A;3.3v@28A Ran my system fairly stably for about 3 days( having problems with XP setup, and still am so I could only run 95,98 on it) but the fact is it ran of for about 3 days then Started turning off every 10 seconds like the others.
Now what I'm really hoping is that someone can tell me what the hell is going on with my machine!Computer runing on low spec 320watt PSU's and not on much higher spec 420watt PSU's, this could only happen in a crappy country like NZ

hi all, Well I ran memtest-86 for 17 hours! and got these results:
test: 0 Errors:0
test: 1 Errors:0
test: 2 Errors:1
test: 3 Errors:498
test: 4 Errors:
test: 5 Errors:12533
test: 6 Errors:27635
test: 7 Errors:26162
test: 8 Errors:863
test: 9 Errors:0
So those are the results. But im wondering if I was meant to run the test for so long cause 6 hours into the test it had NO errors. I could of left the test going for even longer but I got sick of waiting. How do you know when its finished? Also does the test scan only RAM cause it says on the chart:
Pass
16
And there are certainly not that many sticks of RAM in the computer.I'm not familar with memtest so could someone please explain these results.
Note: I took the RAM out of my machine and ran them in another computer.
thanks

Thank you Callum Gordon

Well the term "hotlined" I have never heard before. In any case many states (like NY) just passed regulatory powers to the State Public Service Commission of which it may be called something different in your state. You could file a complaint with them. Or file a complaint with your state attorney generals office, they also take on wireless providers.
The problem here is the staff you speak to are poorly trained, in days gone by it took one call to them and they pulled up your account and see the error and had the authority to remove any errors. They did not remove legitimate account actions, but used their heads instead of putting a customer off or worse lying to the customer.
Its a shame you have to go through what you going through.
Good Luck

Replacing Power Supply Problems

Apple Care had kindly sent me a new power supply. It is a self servicing part, i.e. I have to install it myself. Tried for 2 hours yesterday to get the old one out...didn't work.
The problems:
1. Middle screw on back of power supply does not get loose [the screw close to the power cord connector]. I tried to pull the power supply up while loosening screw...no success. Did anybody run in the same problem...how did you get this screw unstuck?
2. Middle case screw [the one at the bottom of the computer] needs to be turned to the right...which is in contradiction to the downloadable manual...but the front ot the screw still touches the power supply...and possibly holds it in.
How easy should the power supply come out...how much force can I apply without breaking the computer's case?
3. Ambient light sensor connector: comes as separate cable. Since I have not gotten the old power supply out, I do not know how to connect the cable to the new one. There does not appear to be a designated hole on the power supply.
Experiences welcome!
Thanks

Power supply problem a little better after unplugging imac for 24 hours

Hello,
I'm currently having power supply problems (at least I hope it's the power supply and not the mother board), similar to many others I've seen on these boards. What I've noticed is that if I unplug my iMac for about 24 hours I can get it to run again for a little while. Unplugging it for a few minutes (or even 8 hours) doesn't seem to help. My iMac won't get much further than the starting chime before it loses power. But it seems to me that unplugging it for 24 hours has gotten me between 5 days to 5 hours of use before I unexpectedly lose power.
Is there anything to account for this or am I just imagining things? Ultimately, I don't think the answer will help me much, but I am curious to know. I'm taking my iMac to a Mac Genius tomorrow to see if they can help diagnose the problem. I saw a little hit in my video today, which was a first, so I suspect the problem may be getting worse. I'll probably be buying a new power supply soon.

I'm having the same problem. They say to restart you have to unplug the power, wait 10 seconds and then plug it back in but apparently it's not enough. I have to unplug for about 30 seconds, plug back in, and wait anywhere from 30 minutes to several hours before it'll start up again properly. The last time I had this issue was in october '06- when I had a new logic board and power supply put in. Now I'm worried because my applecare is expired by about 3 months. I bought the computer in feb. '05. I hope a new board doesn't cost more than what the computer itself is worth but I'm afraid that'll be the case...

External Drive - Power Supply Problem

Hi All,
I have a problem with my Lacie External HD, i know it's not an Apple product but it is used with my Apple machines and formatted for Apple OS. Also the folks here are very knowledgeable.
I have a Lacie D2 Triple Interface http://salestores.com/stores/images/images_747/301146U.jpg
The drive is not powering up, I have read online that they are know to have Power supply issues since mine went down. I have used the D2's power cable to power up my other external Lacie Mini drive and it is fine. So i can rule the power cable out the equation.
The tiny green light on the power supply is flickering when plugged into the D2 drive.
No blue light on the drive either.
I am prepared to open the drive up and try to fix the power supply, but is there any online guide to doing this? I can't find anything!
Any advice / help is appreciated.
cheers

First thing to try is see if LaCie will replace the power brick, and that is what most people mean by "power supply" issues.
The other is how LaCie products tend to disrupt FW ports and cause problems, which is something that they are also prone to, should not, and don't find with others.
There use to be more attention to hot-swapping FW cable and Isolate brand or feature to prevent a FW port or device from being 'fried' by hot-swapping or plugging in a hot cable.
I'd move my drives to either another Firewire product, or more to native SATA.
http://www.macsales.com/firewire/
Also, the ability to use USB/FW/eSATA (quad interface) means there is a bridge, and that in itself can impose a limit on I/O and how well a drive can talk to the other end. Drives today are faster than even FW800 can deliver.

[PT880-Neo LSR]Power supply problem

Hello,
We've installed the new motherboard today, it model is PT880 Neo LSR. Well we've got everything plugged in, but when we try to turn on our computer it doesn't turn on.
There is a case switch, but when turn on, the fans work for like 1 second then it stop.
I've tried the Troubleshooting guide on the website, and studying the Manual, but I could not find a way to fix this.
Can anyone help us fix this power supply problem please?
Thanks

I only heard a sound psssst, and nothing run. I tested it many time and it still not work. Then I UNPLUG the 4-pin connector from the power supply to the mainboard, and test again, this time, only all the fan RUN except the the fan in the power supply DID NOT run. Is it because that the power supply got problem? I used another power supply 420w to test but nothing run either.

The psssst sound----sounds like something shorted out. Pull everything out and put it back in with a different PSU.
Don't put a hard drive or floppy in-----just CPU, RAM mobo, vid card, fans, PSU-----see if it will post.

I have just replaced my older IMac with a new one because of a cronic power supply problem. Now I see this one is doing the same thing. Is anyone else having the same issues with their MC508LL/A.

I'm with babowa there ... I would suspect the power souce, not the PSU. Where you live could be an issue depending on how reliable and 'clean' the electricity is to your home. If that is ok then it could be the wiring in your house ... if it were mine, I'd need an electrician to check it out.
Personally, I've had computers hooked to my electric service since 1995 and no UPS (despite recommendations) and never encountered a problem with the computers ... many electrical issues (brown outs, outages, etc), just been fortunate they didn't affect my machines.

Asus power supply problems

I am considering a new Asus netbook but have been reading a lot of failure issues on their power supplies going clear back to Sept. Even as soon as December I find people saying they cannot get them replaced because Asus says they are still out of stock. Has anyone got any updated information on this?

As I said I am considering purchasing a new Asus netbook. I do not have one yet. If you look at even the Best Buy customer ratings you will see several with the power supply problem. The internet is full of these complaints on other web sites.

MSI KT3 Ultra-ARU power supply problem

Hello !
I am a lucky owner of MSI KT3 Ultra-ARU motherboard but have one problem. My power supply Fortron (FSP Group) 300-GT 300W seems to have some kind of incompatibility with this motherboard. In my case, the computer can't be shutted down by software. With BIOS version 2.5 it was impossible to shut it down with button too. With 2.6 it is possible to turn the computer off by button but software shutdown still don't work. PSU is working on ALL other boards I have tested so far normally. Somewhere in discussions (not in this forums) I discovered that also some kind of weird sounds occurs with Fortron supply on this board and that it is incompatible. Have anyone some clues to solve this PSU problem ? I am not able momentally to buy some other kind of PSU because Fortron is the only brand from higher category to obtain, so I would be like to solve this.....
Thanks for any info !

PSU is powering Athlon XP 1700+ processor, the other big power consumer is GeForce4 Ti 4200 GPU. I am not able read currents for specific voltage outputs, so I am not able to measure whole power consumption. Computer is working normally, it is NOT overclocked (but it is stable overclocked too) and the only problem is PSU shutdown by software (win & linux, both of them has this problem). From BIOS v2.6 it is possible to shutdown the computer by power button. If it is tried by software, computer resets itself and three beeps occurs.

IMac G5 bluetooth + airport + power supply problems - oh and the dvd drive

Yeah, seems like a lot is going wrong with my mac lately. I bought the iMac G5(no isight) model last year around july. I had some power issues (i.e. leaving the house with it turned on to come home and find it off) For the last year though that was all that was wrong. Once I had to reinstall OS X because it would not find the OS X harddrive during one of these power losses, but that was it.
Then about two weeks ago, I came home to a turned off iMac. I thought the power had gone out in my apartment, but the clocks were all right, and to my surprise the iMac would not turned on. Because I am not under warranty I searched online and found an extended exchange program for my emc model. (http://www.apple.com/support/imac/powersupply/repairextension/) I made an appt at the apple store and they replaced the power supply.
I got the machine back two nights ago and my bluetooth hardware wasn't recognized. And I now had a new "ink" system preference panel in the hardware section which aparently is some sort of handwriting recognition tablet. It ticked me off, but I just wanted to use my computer.
Well today I came home from work and my computer was acting funny. Everywhere I clicked brought up dashboard. This had never happened before and I had no choice but to force a shutdown. Powered it back up and poof, there goes my airport card. No hardware recognized. Now I have a 25 ft cable running the floor of my apartment. This was cause enough to call apple. I was told to make another apointment to bring the computer in. The guy made it sound like it was no big deal to lug a 30 lb bulky computer 40 miles and through a crowded mall. He also made no promises that the repairs would be covered under the exchange program.
I just wanted to hear any suggestions before I decide whether or not its worth it to bring in the computer. Nothing shows up in system profiler under bluetooth or airport. Should I just lie to the "genius" and tell them that my computer still shuts down randomly? I think that way they would at least replace the logic board (which I think is the problem) before telling me to sell my kidney and pay for repairs. I've tried reseting the SMU, and I looked at the bluetooth and airport cards to see if they had been accidently disconnected during the PS replacement. They are actually screwed into the logic board so I think their connections are efficient.
Oh and about the DVD drive. I have to use two cd's in order to burn a single disc. The first disc I put in the drive NEVER works. It spins for about 30 seconds then starts buzzing like blender and spits the cd back out. The second blank disc I put in USUALLY works, but sometimes it takes three discs. This problem has always been there since day 1, but I don't burn enough cd's for it to be an issue.
Thank you for listening to my gripes. I really don't think I'll make the mistake of buying the first issue of a model.
iBook G4 900mghz, iMac G5 20" 2.0 ghz Mac OS X (10.4.8)

OK, first thing -to restore your bluetooth, shut down, unplug for a few minutes and then reboot. Thay usually brings the BT back. You should also repair permissions. Reset your SMU nd your PRAM as well.
Try those four things and please post back,

Mac Pro won't start; power supply problems?

Hi friends, I'm having some very inconvenient hardware problems. My Mac Pro system will not start up. I have done some preliminary searching for similar issues, and it seems there are too many possible outcomes for me to tell directly from their answers. I'm writing in hopes that someone has had the same experience and can offer advice.
Here's my symptoms.
• Mac Pro system, late 2009. Dual Quad-core Intel Xenon, I think. (I usually just go to System Profile, rather than memorise this crap.) Two internal drives (SSD for system, HDD for data); all other hardware standard.
• Power light indicator is solid white. No blinking.
• No startup chime and no audio bleeps
• Display is dark, no activity of any kind.
• This behaviour persists with no network connections, no hardware peripherals outside of Apple Studio display and its associated USB cable (which allows the keyboard)
Do we suspect it's the power supply? It seems to power on, and clicks to life as it does after waking from sleep, but doesn't boot. Pressing the power button again shuts down the machine instantly — no 5-second-hold required.
It could be the RAM, I guess. I have yet to do the diagnosis of removing DIMM pairs one-by-one to see if something is the problem.
Any advice you can offer is great. Thanks

There are LEDs adjacent to the RAM positions that, when lit, indicate a bad DIMM.
The side door is not interlocked, and there are no hazardous Voltages available to your unaided fingers, but components may be HOT.
A Bad DIMM will not preclude Booting. Your Mac will note the defect and attempt to boot without that DIMM. And 2009 DIMMs are independent, so losing one does not take out any others.

Similar problem here. I think it's due to intermittent contact between the pins on the output connector of the ac power adapter and the power receptacle on the laptop.
With the power connector firmly plugged in at the back of the laptop, if I move the connector slightly from side to side, there are some positions where the slightest movement disconnects and reconnects the external supply. This is quite serious because often you need to be sure that external power is connected. For example, at the moment I can't rely on the battery being charged up if I leave the machine unattended.
(I wonder why Lenovo left off the customary LED to indicate when AC power is connected? Without a lamp, it's quite difficult to trouble-shoot problems like this).

Re: Power Supply Problems/ Bad Design

The moderator of this site seems to think that any external power supply can have the same problems as apple powerbook supply. "Not so", say I ! Most PC notebooks and yes, I do use them, have a fairly sturdy cord on both sides of the connection. Should one find oneself in a situation without a power supply for a pc notebook it is usually possible to get one from a local Radio Shack or international electrical store. Not so with apple powerbooks. the connections are specifically apple and although there ae a few generic replacement PSU they are not generally available only from mac speciality stores. Why apple decides to design what is obviously a flimsy (my electrical gaffer on my movie looked at it and just laughed)and possibly dangerous device is beyond me. It occurs to me that with all the innovative design apple has come up with in the past has gone to the designer's heads. Now we are faced with a 'magnetic' connector on the new powerbook pro line. Are you kidding apple ? Please just give us a simple, generic power supply and conmnector so that we travellers can rest in peace knowing we can replace the PSU anywhere in the world.
BTW my PSU was smoking and sparking when I awoke in my hotel room until it just gave up.

Two alternative power adapter manufacturers:

http://eshop.macsales.com/item/Newer%20Technology/APLN2M/
The most common issues people have with Apple's adapters that I've seen are (not that this applies to you, but perhaps one will refer to something you've done that you didn't realize could cause harm):
1. They pull by the cord and not the bulb.
2. They push in without looking.
3. They let the cord bend at the bulb or at the brick. Give it at least two inches of slack.
4. They don't remove the plastic wrapping that is clear from the brick when they first get it. This under the wrong conditions could create an overheating condition.
5. They rely on unreliable power sources. Some older houses have issues with giving reliable power to outlets. Using a backup battery surge protector like those from APC can help.
By the way, my father's Dell power adapter had to be replaced too. Non-Apple notebook power adapters are actually more flimsy than you give them credit for. Part of the problem is designing the transformer to be in such a compressed space that is lightweight too. Until people don't mind the extra weight of a full fledged desktop power supply inside a notebook, thus allowing standard power cables, or a room temperature superconductor is invented, this will be a persistent issue. Take good care of your cords, and don't let them bend so much that they fray.
I might add, I went to Radio Shack, and they had the parts for me to build a power adapter for my Powerbook. Unfortunately the transformer brick would have been 3 times as large and as heavy.

New battery/power supply problems

i bought my ibook on ebay, put in some upgrades and am pretty happy with it. One thing keeps making me extrememly angry. Randomly, without warning, the power supply cuts out. When I look at the port, the light's still on. This wouldn't be so bad because usually the battery would kick in. However, mine came without a battery. So, everytime my power supply cuts, the computer shuts off. What's the problem?

Mike,Check your Energy Saver options (Apple Menu > System Preferences > Energy Saver > Options Tab > 'Schedule' make sure this isn't set to turn off your iBook.
I'd also try resetting the Power Management Unit. (Click this link and follow the instructions).
At least your clamshell's a good deal lighter! (Doesn't it tip back too easily without the weight under the front?).
The problem with running a machine like this is that the Clamshell has no internal battery (unlike every other Mac ever!) this means that you really do need the main battery for correct operation of the system. You'll be forever re-setting date/time etc so it may be worth inv a main battery - even if it's a really cheap one that only gives you 10 minutes run time - it will guard against this type of problem.

Power supply problems with Equium L10

Hi everyone,
When I insert the power cord into the laptop it won't charge up or the indicator will quickly change from battery to power supplied from the plug.
I bought another AC adaptor and I still have the same problem. I wonder whether it is something internally in the computer as it also sometimes makes a high pitched sound (like the sound of a whistle kettle boiling!).
Can anyone offer any advice?
Thank you.

Hi Lauren,
I think the connector for the AC power cable may be loose. When you move the notebook it may be causing the power connector to momentarily break its connection and the notebook will lose all power unless the battery is installed.
You can usually solve this by firmly clamping the power cable to the back of the notebook so that there is no strain on the power connector and it will not be moved or dislodged if the notebook itself is moved.
I made a suitable clamp for my notebook out of a piece of plastic strip which I bent around the power cable and then secured to one of the spare nuts on the back of my notebook with an old screw from a scrap connector. It has worked very well so far and I no longer have problems with my power suddenly cutting out or reverting to battery.
regards,
